The IAG dynamic stall model accurately predicts more pronounced deep stall hysteresis loops when compared with Beddoes-Leishman based models. In his recent publication on the model development, Galih Bangga shows that this is in better agreement with experimental data:

📥To further showcase the capabilities of the IAG Dynamic Stall Model, we have recreated some of the OSU S-809 test using the original airfoil data (as seen in the image). Visit our webpage to download the project file: https://qblade.org/downloads/#Test_Data
